Introduction
The Drucegrove DragonFly™ range of TFT displays are capable of showing elevator position, direction and emergency
messages in addition to other text, images and rich media. This allows the displays to be branded and customised
match the building they are installed in. The additional text and images can be static (ie building name, company
logo, etc), or dynamic based on the position of the elevator (ie individual floor tenancy information).
The TFT20 Series displays are self contained units with the display and driving electronics integrated into one
package. The screen sizes available are 4.3”, 5.7” and 7.0”, and they have the same built in message image library as
the FireFly™ TFT300 Series indicators.
For larger DragonFly™ displays, the TFT500 Omni Driver can be used. This is based on the same driving electronics as
the TFT20 series but boasts a more powerful processor with graphics accelerating and video decoding hardware, and
a DVI / HDMI output. Drucegrove supply a separate open frame TFT screen and a HDMI to DVI cable for connecting
the screen to the TFT500 Omni Driver. The screen sizes available range from 10.4” to 42”, in 4:3 standard, 16:9 wide
or 4:1 panoramic aspect ratios
The TFT20 Series and TFT500 can be networked via Ethernet, which opens up the possibility of streaming live news
headlines, weather, finance information, transport information (TfL, Nation Rail, bus times etc) and more from RSS
feeds.
Live video can also be displayed on displays driven from the TFT500 Omni Driver. The video is streamed digitally to
the display over Ethernet from either an IPTV source or an IP CCTV camera - either of which can be located anywhere
in the building. Being digital, a single video feed can be streamed to an unlimited number of displays without loss of
quality or the need for boosters or amplifiers.
DragonFly TFT20 Series TFT Position Indicators
Drucegrove’s DragonFly™ TFT20 Series Indicators are available in
three standard sizes: 4.3", 5.7" and 7.0". The displays are fully
customisable, and at their simplest level offer a wide choice of
colours, images, character fonts and arrow styles. They are available
with a choice of two different integrated drivers, the RE1 or the RE2.
The RE1 offers basic drawing options with no animation or video. The
RE2 has hardware accelerated graphics allowing smooth animation,
alpha blending and live video playback.
The position indicators may be configured for elevator car or landing displays, and are capable of showing up to
three character floor designations, car direction arrows, hall lantern arrows, full screen messages and pictograms.
They are fully compatible with the Drucegrove 2-Wire™ System and OTIS® Serial Data, and may also be used as
stand-alone position indicators with binary, Gray or discrete wire-per-floor inputs.
Every aspect of the display can be configured, and special display content can be configured to show or change at
certain floors, for certain message responses, or even for a specific time of day or date.
The position indicators can be configured over a LAN via a standard web browser, or alternatively the on-board
micro SD card can be removed and reconfigured freely from any computer.

DragonFly TFT500 TFT Screen Driver
The DragonFly™ TFT500 Omni Driver works with any readily available
DVI or HDMI display, so if our standard range of sizes is not enough,
choose another! For interfacing to your elevator, the Omni Driver
connects to either the Drucegrove 2-Wire™ System, OTIS ® Serial Data,
or with the addition of an IND059 input mode, non-proprietary binary /
Gray / discrete signals. The unit can be networked via RS485 and
Ethernet for live data feeds and live network video streams.
Take advantage of their most sophisticated features. Use the latest technology in processing graphics to combine
elevator information with scrolling text feeds, rich media and video content. Our in-house team will take your
concept, images and logos to produce a result that suits your building. And with the open connectivity that we have
provided you will never be out of date.
We can supply any size of open-frame TFT display, with a lens and any mountings and faceplates needed for fitting
inside your elevator cars, and all necessary networking peripherals for connecting together a system of displays.
Our in-house metalwork facilities allow us to mount any display in almost any location with a professional finish and
minimal hassle.
For basic operation, the TFT500 simply needs a 2-Wire input for power and elevator data, and a screen connected to
the HDMI / DVI output. For data synchronisation and live data or video feeds, the Ethernet Network would need to
be connected:
TFT500
2-Wire Supply Input
Two pairs of + and - terminals are
present for Loop In / Loop Out
2-Wire connectivity
Ethernet Network
HDMI / DVI Output
Connect HDMI-to-DVI cable

DragonFly Driver Hardware and Operating System
The DragonFly hardware is based around an ARM Cortex processor, and runs the Microsoft Windows CE 6.0
operating system. The hardware and operating system were specifically designed for embedded industrial
applications. There are no mechanical drives –all storage is flash based. The hardware does not require active
cooling, and is not damaged by power loss or cycling –even if the boot sequence is interrupted. If power is lost and
restored, the DragonFly will automatically reboot and recover without issue.
Internally, the DragonFly has a non-volatile flash drive which contains basic boot loader software. This boot loader
runs the main DragonFly software automatically on power up. The main DragonFly software and all relevant layout
and configuration files are stored on a removable micro SD card (refer to individual product wiring diagrams for
micro SD card location).
The TFT20 series DragonFly driving hardware can either be built around the RE1 or the RE2 engine. The RE1 offers
basic drawing options with no animation or video. The RE2 has hardware accelerated graphics allowing smooth
animation, alpha blending and live video playback.
There are no engine options with the TFT500, and hardware accelerated graphics is available in this unit by default.
DragonFly Display Settings
The TFT022, TFT023 and TFT024 have an integrated screen with the following resolutions
TFT022 has a 4.3” screen with a resolution of 480×272 pixels
TFT023 has a 5.7” screen with a resolution of 640×480 pixels
TFT024 has a 7.0” screen with a resolution of 800×480 pixels
The TFT500 Omni Driver can be configured to output any resolution on its DVI output. The resolutions of the
standard screen sizes are as follows:
10.4” screen has a resolution of 1024×768 pixels
15” screen also has a resolution of 1024×768 pixels
19” screen has a resolution of 1280×1024 pixels
Note: All DragonFly screens are driven at 16 bit colour depth (RGB 5-6-5) by default.

Drucegrove DragonFly User Manual 1.4 Page 10
DragonFly Core Software and Configuration
All software configuration, fonts, images, data files, etc are stored on the micro SD card:
The core software itself is stored under the “\Storage Card\Bin\” directory.
All of the software and layout settings are stored in XML files under the “\Storage Card\Config\” directory.
Layouts are stored in DFX files under the “\Storage Card\Config\Theme\” directory.
Other data is stored under “\Storage Card\Data\”. This includes fonts, and the message image library files.
The software and configuration are automatically set up on the micro SD card by the DragonFly Designer software.
The same DragonFly core software works on all TFT20 Series and TFT500 hardware, regardless of the processor
engine or screen type.
DragonFly Boot Sequence
The RE1 based DragonFly has no internal flash, so its boot sequence is as follows:
1. A registry key is present to automatically run “\SD Card\Startup\Startup.exe”
2. Startup.exe sets up the desktop environment, installs any default fonts, configures the Ethernet network,
initialises the data receiver firmware, and finally runs “\SD Card\Bin\DragonFly.exe”
3. DragonFly.exe shows a white splash screen with a DragonFly logo as it loads, before finally displaying the
screen layout selected in the Settings.xml file.
If the Startup.exe software does not automatically run after creating a new SD card, it will need to be manually run
the for the first time using a USB mouse/keyboard and the Windows CE file explorer. Double click on Device,
followed by SD Card and then Startup. Then double click on Startup.exe. The software will automatically create the
auto-run registry key for the next time the device boots up.
The RE2 and RM2 based DragonFly has the Startup.exe software pre-installed in internal flash, so its boot sequence
is as follows:
1. Startup.exe is run from the internal flash, and installs any default fonts, configures the Ethernet network,
initialises the data receiver firmware, and finally runs “\Storage Card\Bin\DragonFly.exe”
2. DragonFly.exe shows a white splash screen with a DragonFly logo as it loads, before finally displaying the
screen layout selected in the Settings.xml file.
As a failsafe, The Windows CE image on the RE2 and RM2 will also launch “\Storage Card\Startup\Startup.exe”
automatically. This instance of the software will check the internal flash instance and replace it if it is not fully
present or has not executed in a timely manner.
If there is no micro SD card inserted, the Startup.exe software on the internal flash will not find “\Storage
Card\Bin\DragonFly.exe”, and will show an error message on the screen. The unit will then automatically reboot
itself after 2 minutes.
